SPECIFICATION forming part of Letters Patent No. 488,215, dated December20, 1892.

Application filed August 24, 1891. Serial No. 403,626. (No model.)

To aZZ whom, it may concern.-

Be it known that I, GEORGE D. MUSSEY, a citizen of. the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Ice-Creepers; and I dodeclare the following to be a full, clear, and

exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in ice-creepers;and it consists in a certain construction and arrangement of parts, ashereinafter fully set forth, the essential features of which beingpointed out particularly in the claims.

The object of the invention is to provide a simple and effective device,adapted to be secured to the heel of a shoe, that will prevent slippingon the ice, and in which the arrangement is such that the engaging-spurmay be readily projected or withdrawn, when desired, without removingthe device from the heel. This object is attained by the constructionillustrated in the accompanying drawings, in which;

Figure 1 is a perspective view of a shoe, showing my improved deviceattached to the heel thereof. Fig. 2 is an enlarged plan view of thedevice. Fig. 3 is longitudinal section through Fig. 2.

Referring to the letters and figures of reference B designates theoblong metal baseplate, which is provided with the countersunk holes 0that receive the screws for attaching it to the heel.

O designates an elongated spring-plate or arm provided at one end withthe spur-head a, which is eccentrically pivoted to the plate B at thelongitudinal center of said plate, by means of the pivot c. The oppositeend of said arm being provided with a hole 2 that receives the pins 3set in the plate B at each end, whereby said arm is locked in positionwhen adjusted, the spring portion t of said arm yielding sufficiently topermit the free end thereof to spring outward so as to ride over the endof said pin until it enters the hole 2 in said arm, when the tension ofsaid spring will securely retain said parts in the locked position.

The plate B is secured to the front vertical face of the heel H, so thatits lower edge will stand flush with the bottom of said heel, asclearlyshown in Fig. 1. In which positio'mby throwing the pivotedspring-arm (J to the left, and looking it as before described, thespurpoint a. will be thrown down or projected beyond the bottom of theheel, clearly shown in Fig. 1, and by dotted lines in Fig. 2, andsecurely held in that position. lVhen said spur will engage in the iceand prevent slipping, as will be readily understood. To withdraw thespur, the arm 0 is unlocked and swung outward to the right, whereby thespur-point is turned upward, as shown in Fig. 2, and by locking the arm0 over the pin 3, the spur is secured in that position, where it isentirely out of the way, and in no manner interferes with walking.

Instead of one spur-point, two or more points may be employed, asdesired.

It will now be apparent, that this improved device is simple andinexpensive, and that when secured to the heel,'the spur may be quicklyand easily projected or withdrawn, when desired.

Having thus fully set forth my invention, what I claim as new and desireto secure by Letters Patent, is;

1. In an ice-creeper, the combination with the base-plate, said platehaving a projection at each end thereof, of the swinging springarmhaving a spurred head at one end, said head being pivoted to thelongitudinal center of said base-plate, the free end of said arm beingadapted to spring over and engage the projections on the base plate tolock it in position.

2. In an ice-creeper, the combination with the base-plate having meansfor attachment to the shoe and provided with a pin at each endprojecting from the face of said plate, of the swinging-armeccentrically pivoted at one end to said plate, said arm having a spurat its pivoted end, and a hole in its free end that receives the pins ofthe base-plate, as and for the purposes specified.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE D. MUSSEY.
